A program that would usually take me a few hours to make i am on day 5, 4 and a half of which have been trying different ways to get it to update, and not one of them will post the information back to the SQL 2000 database I am actually going insaine.
The best i can get out of it is this error. "Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information" I have googled it and come up with the fact the primary key isnt set right, but i still cant get that to work. Here is the peices of code that are relevant.

I have a container with different controls in it. This container can be shown 1 or more timeson a form. The number of times is not known when the application is build.So form with the number of containers must be generated by code. When the number of containers is high a scroll bar must be shown.My idea was to use the control TableLayoutPanel. The first row consists of the container with it's controls. When loading the form a number is calculated. This number is used to show the number of containers.

Error Message: "This server version is not supported. Only servers up to Microsoft SQL 2005 are supported VB.NET" I am using VB.NET 2008 and attempting to connect to SQL Server 2008 with XP as the operating system. I have service pack 1 installed in Visual Studio but this error message presists. The articles I have read on this error said to install sp1 as a solution but I have done that and the error persists. FYI, the error does not occur when I am using code to connect to SQL Server but when I attempt to connect using one of the designer wizards this error occure.

My users are getting this error when trying to update the database:
"Concurrency violation: UpdateCommand affected 0 of the expected 1 records"
All the users are doing is clicking a button which updates a record.No two users are updating the same record or even within the same column. They could be updating within the same row but still not the same record.It seems to be happening when the program is open for a little while and they come back and try to update the database through the program. I have read a little bit about this error but none seem to lead to a clear solution.It seems like the database connection is timing out due to inactivity?Here is my update command:

I'm trying to update a Access database. I'm new to this and I've reviewed an Ado tutorial early today. I'm trying to apply what is taught but I'm getting an error message and I can't seem to get passed it.
In my code I have an Add, Update, and Delete process. The Add and Delete processes work just fine. It is only when I go to update the database that I get the following message."Concurrency violation: the UpdateCommand affected 0 of the expected 1 records."

Update requires valid UpdateCommand passed DataRow collection modified rows. When I run the following code. But the strange thing is that I have similar code on another form and it works great. The only difference is the database table is different. I verified both tables and they look identical, as far as settings. I have verified that _Non_MS_Office_Licenses has a primary key that is unique. Looking in dataset manager I see the query for fillBy() is fine and it has all the insert and update stuff. At the end when it verifies it says all is verified when I configure the dataset
Dim row = FrmApp.Non_MS_Office_LicensesBindingSource.Current
row("Primary User") = Replace(CStr(TxtUserid.Text), "'", "`")
row("Staff Last Name") = Replace(CStr(TxtLastName.Text), "'", "`")
row("Staff First Name") = Replace(CStr(TxtFirstName.Text), "'", "`")

I've got a simple mdb database set up in Visual Basic Express Edition (winforms) and I'm trying to update data from a datagridview to a database. I've databinded the textboxes to the columns I want in the datagridview and this works great. After some struggling, I've finally managed to have the values updated in every row of the database. But, trying to modify a newly created record throws this error:
"Concurrency violation: the UpdateCommand affected 0 of the expected 1 records"
I mean, it seems as though the error only happens with newly created rows. Because closing the application and reopening it immediatly, I'm allowed to update the values of the cells.
I also noticed that the ID of the row is set to "-1" when I've just created a new row. The other rows don't have a negative number for ID. Could this be the cause? Seems as though the row isn't really updated to the database.
So this is the code for the AddRow button
Dim newRow As MusicDBDataSet.SongsRow
newRow = MusicDBDataSet.Songs.NewSongsRow()
newRow.Name = txtBoxNewName.Text
newRow.Genre = txtBoxNewGenre.Text
newRow.Rhytm = txtBoxNewRhytm.Text
[Code] .....
But thinking about it, the textboxes used to update the values of the newly created row are databinded to the database or tableadapter itself right? Could it be that the UpdateCommand fails because the row hasn't really been created properly yet?

I'm having trouble updating a sql server database with a dataset using a dataadapter. I have used the dataadapter with success in the past when adding new rows, using a single table, and just calling the dataadapter.update command.However, I am now running into a more complex scenario and I need to use dataadapter.UpdateCommand method and I'm having lots of problems.
The sql statement that I'm using to fill the dataset looks like this: "Select [Order Details].ProductID, [Order Details].UnitPrice, [Order Details].Quantity, [Order Details].Discount, Products.ProductName From [Order Details] INNER JOIN Products ON [Order Details].ProductID = Products.ProductID Where OrderID='" & strOrderID & "'", sqlConn"
This is pulling the data from 2 different tables (Order Details and Products) and then joining them and filling the dataset, and I am seeing the exact results I want. I am then binding the dataset to a datagrid control that allows the user the option to edit the datagrid, which in turn updates the dataset.
So that being said how do I get the updated dataset back into the database? I tried using dataadapter.update but it informed me that I now need to use dataadapter.UpdateCommand. Ok, so I've looked up how to use UpdateCommand but I cannot for the life of me figure out how to set up the right sql command statement. Part of what has me confused is the UpdateCommand examples I have seen are working with a specific row and updating that rows data. I can get that to work but I want all changes to the dataset to persist and update to the database when the user is done working on the datagrid.
Also, the examples shown set up command parameters but again, this is only confusing me because I just want to send the whole dataset back to the database. It seems like the parameters are saying "Ok, this specific row in this specific dataset.table, update these specific fields in this specific database". I'm not sure how to accomplish that when working with a datagrid.

I am trying to check for concurrency when updating a record in the database. Here is my current VB.NET code and Stored Procedure code to do the update.
When a user changes a Status column value the DataGridView CellValidating event is fired and in that event it try's to update the record in the database using the stored procedure. The update works, but my SqlDataAdapter doesn't update dtmUpdateDatetime in dtResults. My UpdateDatabase function uses dtmUpdateDatetime to check for concurrency.

What's the syntax for an Update query for a table without a primary key?Disclaimer: Frustratingly, adding a primary key is not an option. My program is a small program in a much larger system with poor data management. My development time does not include rewriting the other software.
Note: The database is Microsoft Access.
Note: Similar to: Excel: TableAdapter UpdateCommand for table without primary key
UPDATE: Am I correct in saying, "If the table in the database has no explicit primary key, then there can be no valid TableAdapter UpdateCommand?"

None of the "answers" that I have been able to find, address the problem. I am using oledb to read and update a MS Access DB in an ASP.NET application.I read the member dataset and fill it using the data adapter.I modify the row of data in the dataset.I then use the data adapter to update the row and get the error shown in the subject.
I am an experienced developer using ado.net on sql server windows application via the data adapter, so am familiar with how this should work.
I have searched everywhere and am hoping that someone here at Microsoft might have the answer.

I have a table in Access with two key fields (let's call them Item and Cust). These key fields *combined* are the primary key. So each record must have a unique Item and User combination. It can have a duplicate Item with other records, and a duplicate Cust with other records, but not a duplicate of both. Because my "primary key" is a combination of two fields, I can't make a primary key on the table in Access (it only supports one field as a primary key).
I have another table in SQLServer which also has Item and Cust, but in addition, is has several descriptive fields that give more details about the Item and Cust. I'm trying to use ADO.NET to bring in that SQL Server table and UPDATE some matching fields in Access with the descriptive fields. [Code]
